I'm not sure what would cause the IDs to be reported differently, unless there's some sort of race situation with one driver loading before the other - if you reboot the official release does it always load the driver in the same order?
it's definitely not a kernel version issue - as I mentioned before, I had to blacklist snd_soc_skl starting back when I first started running your 9.0 nightly/test builds (probably last summer?), which is why I was surprised when others reporting it wasn't needed with the official 9.0 alpha/beta/release builds (which I've subsequently verified myself). so this has been an issue that's persisted across many major and minor kernel versions.
The release builds reliably load the correct driver (snd_hda_intel), and your builds reliably load the incorrect one. I started looking at how to debug the HD-audio driver, and might need to do a debug build with additional options enabled to get more info, since right now I get absolutely nothing in dmesg when the incorrect driver loads/attaches
